What does 12070 mean in terms of the circulatory system?
120/70 is a common blood pressure measurement, with the first number (systolic) representing the pressure in the arteries when the heart beats and the second number (diastolic) representing the pressure when the heart rests between beats. A blood pressure reading of 120/70 is considered normal and indicates good circulatory health.
What blood vessel in fetus contain the most oxygen?
In the umbilical cord you have one vein and two arteries. This vein goes to the liver of foetus. This blood vessel contains most oxygen and food in case of foetus. After birth this vessel gets obliterated to form the falciform ligament.
How does the circulatory system connect to the nervous system?
The nervous system sends a signal to the heart to make it beat. I also helps control not just the beat, but also the blood pressure as well. The part of the brain that controls the heart beat is the medulla oblongatta in the brain stem.
Which blood vessel has a pulse?
Arteries have a pulse due to the rhythmic contraction of the heart, which creates a pressure wave that can be felt as the pulse in arteries. Veins do not have a pulse as they carry blood back to the heart at a lower pressure.
What is the difference between oxygenated blood and deoxygenated blood?
oxygenated blood is basically blood (Red blood cells) with Hemoglobin in the oxygenated state i.e with O2 molecule attatched to it. and naturally deoxygenated blood is without oxygen.
Oxygenation occurs when blood flows through the lung and the oxygen from the respired air diffuses across the alveolar epithelium and capillary endothelium barrier into our RBCs
its a very simple differentiation not requiring a very complex explaination
The blood now rich in oxygen re enters the heart though the pulmonary?
When blood that is rich in oxygen re enters the heart, the blood enters through the pulmonary valve. The pulmonary valve brings the oxygen rich blood to the pulmonary trunk of the pulmonary artery.
What is the function of the aortic valve?
The aortic valve functions as a one-way valve between the heart and the rest of the body. Blood is pumped from the left ventricle of the heart, through the valve, and down the aorta, which in turn supplies blood to all of the organs in the body. Between heart contractions, the valve closes, preventing blood from flowing backwards into the heart. The function of the aortic valve is then twofold: (1) It provides a route for which blood can leave the heart, and (2) It prevents blood that has already left the heart from leaking backwards into the heart.
Examples of nonvascular plants include mosses, liverworts, and hornworts. These plants lack specialized tissues for transporting water and nutrients, so they are typically found in damp environments where they can absorb water directly from their surroundings. Nonvascular plants reproduce through spores rather than seeds.
What three things make up the circulatory system?
The circulatory system is composed of the heart, blood vessels, and blood. The heart pumps blood through blood vessels to transport oxygen, nutrients, hormones, and waste products throughout the body.
'c' heart pumps oxygen rich blood,
'a' oxygen rich blood arrives at capillaries,
'd' oxygen moves through capillary walls,
'b' oxygen enters body cells.
Vascular means pertaining to vessels which transport fluids (whether in plants or animals).
In plants, phloem and xylem are vessels that carry water and food through the plant.
In animals, arteries and veins carries blood
Severing the sympathetic nerves can help by interrupting the pain signals traveling to the brain from the left lower leg. This procedure can reduce the perception of pain in the affected area, allowing the individual to walk without experiencing severe pain.
What are tiny blood vessels called?
Tiny blood vessels are called capillaries. They have thin walls that allow for the exchange of oxygen, nutrients, and waste products between the blood and surrounding tissues.
What is the air mixture in scuba?
The air mixture in scuba diving tanks is typically compressed air, which consists of about 21% oxygen and 79% nitrogen. This mixture allows divers to breathe at depth without experiencing adverse effects of high pressure.
If the body's immune mechanism is not capable of fighting then the bacteria produces disease.
Which human blood group lacks proteins in the red blood cells?
Blood type O lacks the antigen proteins of A and B. Blood type O is the universal donor.
How are red and white blood cells alike?
== == Platelets: surface when you get cut and clogs the bleeding (scabs) white blood cells: fight against bacterias and viruses
red blood cells: Carry "food" and oxygen == ==
their both in your body, they both can only be seen through a microscope, their both cells(blood), they both benefit your body, and you need them both to survive that's all i could think of
All i know about red blood cells is that they are part of your first line defence. White blood cells on the other hand are your second line of defence and they find diseases/pathogens and find them, some may just 'eat up' the pathogens but others will make antibodies which put antigens on the pathogens and kill them.
That is what i think as i have just done about it in science! Year 8
well it is quite obvious whrn you think about it.............THEY ARE BOTH CELLS. see the simplist way of doing it just think what they both have in common plus blah blah blah blah blah!EASY!!tfjtfhbdgffhg
Why do you need red blood cells?
Red blood cells are vital in our bodies because they are solely responsible for delivering oxygen to the organs in our body. If we didn't have any red blood cells, we wouldn't last 5 seconds because our organs will shut down due to oxygen deprivation.
Red blood cells contain an important component called Hemoglobin. This protein contains iron and carries oxygen. The lungs play an important role because they allow oxygen to diffuse into the blood cells. The blood cells are then pumped along with the rest of the blood throughout the body where they transfer the oxygen to each of our organs.
What sort of circulation system does a fungi have?
Neither! Protists are mainly simple organisms made of a single cell. They are small enough to obtain their oxygen and remove wastes by diffusion. Diffusion is also rapid enough to distribute substances inside the cell. Therefore a circulatory system is not needed. No a fucn circulkatory sdmaskjofnmdsijp fadsm [fas fcds
See http://en.wikipedia.org/wiki/Protist
However Fungi are not protists.
White blood cells are the "army" of the circlulatory system-they guard against infection, fight parasites, and attack bacteria. Red blood cells only transport oxygen. White blood cells have more function. There are different kinds as well including phagocytes, allergy attacking cells, and a special class known as lymphocytes which prouce antibodies that are proteins that help destroy pathogens. I hope this helped a little.
The bodily system consisting of the heart, blood vessels, and blood that circulates blood throughout the body, delivers nutrients and other essential materials to cells, and removes waste products. Also called cardiovascular system.
Circulatory system is the transportation system, made-up of Heart, Arteries, and veins.
The main organs of the skeletal system and what are their functions?
The main organs in the skeletal system are bones.
Their functions are to protect the bodies organs, and keep our shape the skull protects the brain from brain damage.
The bones are
White blood cells are a crucial part of the immune system and are responsible for fighting off infections and foreign invaders in the body. They help to identify and destroy pathogens such as bacteria, viruses, and fungi, helping to keep the body healthy and protected. There are different types of white blood cells, each with specific functions in the immune response.
How does the nervous system work with other systems?
The autonomic nervous system, dividing into sympathetic and parasympathetic nervous systems, controls the involuntary life-sustaining functions of the body. It controls heart rate (keeping the heart beating properly), blood pressure (through vasoconstriction and vasodilation), adrenaline release for glycogen breakdown to glucose to aid fight-or-flight responses, digestive system parastalsis, and even glandular release for digestion, immune response, etc., interacting with other hormone systems.
The central nervous system interacts with the skeletomuscular system via motor control, as well as reflex feedback. It receives sensory input, processes it, and responds.
Since a critical part of the brain is the hypothalamus, and the hypothalamus interacts with and controls the pituitary gland (the master gland of the endocrine system that controls all of the body's hormone systems), the brain also controls the endocrine system.
