Answer:
The semilunar valves prevent backflow of blood into the ventricles.
Explanation:
The semilunar valves are valves found at the junction between the left ventricle and the aorta and also between the right ventricle and the pulmonary artery. They are cup-like in shape and prevent blood from flowing back into the ventricles which are the pumping chambers.
There are two types of semilunar valves. The aortic semilunar valves and the pulmonary semilunar valves. They are made up of the endocardial and connective tissue.
The closure of the semilunar valves causes the second heart sound detected on the stethoscope.
Diseases that arise from the semilunar valves are caused by its stenosis which is the narrowing of the valves and regurgitation where the heart valves can no longer hold firm enough to prevent the backflow of blood.
After the digestion of carbohydrates, fats, and proteins in duodenum, the digested nutrients are absorbed in the ileum.
Ileum is a section of the small intestine, after duodenum.
Food is absorbed by diffusion and active transport. Villi on the walls of the ileum helps this process, since it can increase its surface area and provide a good blood supply, thus increase the rate of absorption.
Note that water can also be absorbed in the large intestine, those water absorbed there are the ones that cannot be absorbed in the ileum.
However, not all water is absorbed as we can notice that faeces are wet.
