Human Anatomy and Physiology

Parent Category: Biology
Human physiology is the study of the human body relevant to the functions of the organs and systems. It provides a biological baseline for the five senses including the different systems, so that the body can operate normally.
The heart circulates both oxygenated and deoxygenated blood butalong different paths - the human heart has 4 chambers which enableit to do this.
Thank you for your question. My answer is "No." However, an injury to the cervical spinal nerves or those evenlower, like an injury to the axillary (armpit) nerves or those inthe elbow region can cause the symptoms of a pinched nerve withpain in the wrist. Pain would be located at the nerve injury...
Abdominal pain and loss of appetite are very unspecific symptoms.They can stem from pretty much any disorder in thegastroinstestinal tract, and even from disorders elsewhere in thebody.

The skeletal system has a few important jobs. One is to keep usfrom becoming blobs of human tissue similar to jellyfish butwithout the water. The other is to protect vital organs such as ourbrains, heart, lungs, liver. But they have another role which is tocreate a form on which everything else can...

You have to go to a surgeon
There is 1 skull in the body last time I checked.
It is here that messages from the eyes are interpreted.
Cranial nerves that have a motor function tend to be bilaterally innervated . In other words, the rightaccessory nerve (XI) receives input from both the right and theleft motor cortex. The same goes for the left accessory nerve. This is a handy advantage in strokes, since upper motor neuronelesions...
This could be down to a lack of fruit consumption. This happened toa cousin of mine and the doctor said more fruit and veg should beeaten. If you're really worried go to the doctor. Hope this helped!
Yes! Lets take an example, we are exercising and our breathingsystem is working, other systems will also work like muscularsystem will work, it will help the body to move around. Nervoussystem also function, it'll help you to run by giving sensoryimpulses to foot, and to heart to pump blood. So...
Clostridium tetani , the bacterial pathogen that causes tetanus (lock jaw) is arguably armed but is definitely dangerous. The toxin excreted by this bacterium causes serious illness and death in humans, but it is arguable whether that toxin can be considered an intentional weapon, since it serves...
You can think of blood as a combination of (salt) water. proteins,and red blood cells.. The water carries everything that's water soluble. The proteins carry the fat soluble stuff. And the RBC's carry oxygen.

The part of the hip bone that forms the hip joint is actually formed from two of the three fused paired bones - the ischium and the ilium, which are shaped into the acetabulum. The distal articulating bone is the femur, specifically the head of the femur. Femur & coxarum form the hip joint. The hip...

The blood is able to move to and from the heart through thecontraction of the heart muscle. These contractions build uppressure and cause you to have what is commonly known as bloodpressure. That build up of pressure pushes the blood throughoutthe arteries and veins and enables it to circulate...
Fibrous connective tissues are found in cartilage, ligaments, and tendons. Cartilage prevents adjacent bone ends from grinding together during movement, tendons attach skeletal muscles to the bones and hold the bones in close proximity, and ligaments are similar to tendons but have the elasticity...
Oxygenated blood is the blood remaining after the oxygen intake bythe body from the blood. And than oxygenated blood goes to Lungsand heart with enrich with oxygen for the body.
Muscles contract when they receive nerve signals from the brain,telling them to put filaments in action. The thin ones slide pastthe thick, shortening the sarcomere (this is a special part of themuscle).
Your blood is never truly dexoygenated, but as it delivers oxygen to tissues the saturation of oxygen gets lower. When the blood reaches the alveoli of the lung oxygen diffuse from the higher concentration of the air to the lower concentration of the blood, where most of it binds to hemoglobin...
Veins that draw blood from the brain are called dural venous sinuses. They receive oxygen-poor blood from the brain and pass it on to either the sigmoid sinus or the inferior petrosal sinus, which then pass the blood to the internal jugular vein, in the neck.
The pancreas is a glandular organ with two main functions. It functions as an exocrine organ by producing digestive enzymes, and as an endocrine organ by producing hormones. The pancreas secretes digestive enzymes such as proteolytic enzymes which are responsible for the digestion of proteins,...

The hydrolytic process breaks down inter-amino acid bonds of the protein, so that first polypeptides, then oligopeptides, and finally the constituent amino acids result. By hydrolysis a water molecule will be split into a hydrogen atom and an -OH group and these two units take the bindings that...
difference between an antibody and an antigen
No immunoglobulins (Igs) provide that! That is because Igs or antibodies are in blood tissue and circulated all over blood and immune system. The mucous membrane and skin are actually functioning as a physical barrier preventing invading microbes.
Arms and legs are known as appendages.
Bile is often green because of the presence of biliverdin, which isa breakdown product of haemoglobin.

Sarcopenia, defined as age-associated loss of skeletal muscle mass and function, often reduces muscle mass by about 30% from early adulthood to age 80, usually at a rate of 0.5% to 1.0% per year. There are many factors, such as the individual's activity level and rate of metabolism, involved in the...
