Circulatory System

A vascular system distributes nutrients etc. and removes waste from the cells of the body. In humans this is controlled by the heart pumping blood around the body which is called the cardiovascular system. These systems are often referred to as the circulatory system.

Yes, humans do have a vascular system. It consists of arteries and capillaries that carry oxygenated blood to the heart and other organs, veins that carry de-oxygenated blood from the organs to the lungs and then the heart for circulation. With age, veins may begin to lose their elasticity and strength. Veins, too, need a balanced diet to support their healthy functions. A good blend of nutrients, antioxidants and herbs help to keep veins strong and flexible supporting healthy circulation of blood throughout the body. Veins carry nutrients and oxygen that are required for the proper functions of all our organs. You can support vein health by taking supplements like Vein Matrix. The important herbs are horsechestnut, butcher's broom, Vitamin C.

Factors that directly influence venous blood flow include venous pressure, intrathoracic pressure changes during respiration, skeletal muscle contractions, venous valves, and sympathetic nervous system activity. These factors help propel blood back to the heart against gravity.

The circulatory system of a crocodile is similar to that of other vertebrates. It consists of a heart with four chambers (two atria and two ventricles) that pumps oxygenated blood to the body and deoxygenated blood to the lungs to be oxygenated. Crocodiles have special adaptations in their circulatory system that allow them to hold their breath for extended periods while submerged.

The respiratory system brings oxygen to cells. Oxygen is inhaled through the lungs, where it diffuses into the bloodstream and is transported by red blood cells to cells throughout the body. There, it is used in cellular respiration to produce energy.

It takes about 1 minute for the heart to circulate blood through the entire body.

The heart needs a combination of cardiac muscle tissue for contraction, nervous tissue to help regulate the heartbeat, and connective tissue to provide structural support. Having only cardiac tissue would limit the heart's ability to function properly and regulate its rhythm efficiently. The different types of tissues work together to ensure effective pumping of blood throughout the body.

the blood comes in the through the superior and inferior vena cava. it then passes through the right atrium and is pushed through by the bicuspid valves. it enters the right ventricles and exits the heart through the right semi lunar valves and the pulmonary arteries and into the lungs. it is then brought back in through the pulmonary veins and passes through the left atrium. it is pushed through by the bicuspid valves and into the left atrimu and exits through the left semi lunar valves and out through the aorta to the rest of the body.

No, an allergy is an immune system response to a substance that the body perceives as harmful. It is not directly related to the circulatory system, although allergic reactions can sometimes involve increased blood flow and inflammation in the affected area.

the cardiovascular system needs the skeletal system because the skeletal system protects the organs of the cardiovascular system with the ribs and other bone parts. Also bone produces erythrocytes (red blood cells) and leukocytes (white blood cells) which of course are essential for the cardiovascular system

The structure you are referring to is likely the coronary sinus. It is a collection of veins that drain deoxygenated blood from the heart muscle itself back into the right atrium of the heart. It serves as the main venous drainage for the heart.

The circulatory system is responsible for transporting oxygen, nutrients, and hormones throughout the body via blood vessels. The nervous system controls voluntary and involuntary actions by sending electrical signals through neurons, allowing for communication between different parts of the body and the brain. Both systems work together to maintain homeostasis and ensure proper functioning of the body.

The aortic arch arches to the left as it emerges from the heart.

The coronary arteries are the blood vessels that supply glucose and oxygen to the heart muscle. These arteries branch off the aorta and encircle the heart, delivering nutrients and oxygen-rich blood to support proper heart function.

The heart pumps blood throughout the body by contracting and relaxing to create pressure that pushes the blood through the blood vessels. Arteries carry oxygen-rich blood away from the heart, while veins carry oxygen-poor blood back to the heart. This cycle of blood flow helps deliver oxygen and nutrients to cells and remove waste products from the body.

It goes through the pulmonary artery, to the lung. Becomes oxygenated, and goes to the left atrium. It is pumped through the Mitral valve, into the Left Ventricle. Left Ventricle pumps it through the aortic valve to the aorta.

The first animal phylum to have a circulatory system was the Annelida phylum, specifically the earthworm. Annelids have a closed circulatory system composed of blood vessels that transport nutrients and oxygen throughout the body.

The structures of the circulatory system include the heart, blood vessels (arteries, veins, and capillaries), and blood. The heart pumps blood through the blood vessels to deliver oxygen and nutrients to cells and remove waste products. The blood vessels transport the blood to and from the heart, while capillaries allow for the exchange of substances between the blood and tissues.

The respiratory and circulatory systems meet at the alveoli in the lungs. Oxygen from the air in the alveoli diffuses into the bloodstream, where it is carried by red blood cells to the rest of the body. Carbon dioxide, a waste product of metabolism, is picked up by the red blood cells and transported back to the lungs to be exhaled.

No, the heart pumps blood through the body using its strong muscle contractions. The circulatory system is responsible for transporting the blood to all parts of the body, including delivering oxygen and nutrients and removing waste products.

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.

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.

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.

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
