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.
Answer:
Fertilization
Explanation:
Cell division is the process that occurs in all living organisms by which a cell divides into two or more daughter cells. The purpose of vegetative cell division (mitosis) in eukaryotes is maintenance of the cell's genome, growth by cell multiplying and tissue renewal by producing new cell. Reproductive cell division-meiosis is responsible for the formation of gametes for the further reproduction. In prokaryotes it is used as a form of reproduction ( binary fission).
<u>Answer:</u>
<em>Carbohydrates are stored in the liver and skeletal muscles in the form of </em><em><u>Glycogen.</u></em>
<u>Explanation:</u>
The carbohydrates are stored in the form of fats when the muscles and liver are full. When we consume carbohydrate giving foods, the food is broken down into molecular form of sugar and the sugar is turned into glucose by liver.
The glucose is converted into glycogen for long term storage in our body. The glucose is converted into fats and stored in body when the liver and skeletal muscles are full.
