Answer:
Explanation:
1.In order to survive, all living things need air, water, and food.
2.The circulatory system consists of three independent systems that work together: the heart (cardiovascular), lungs (pulmonary), and arteries, veins, coronary and portal vessels (systemic).
3.White blood cells are part of the body's immune system. They help the body fight infection and other diseases. Types of white blood cells are granulocytes (neutrophils, eosinophils, and basophils), monocytes, and lymphocytes (T cells and B cells).
4.Plasma is the liquid portion of blood. About 55% of our blood is plasma, and the remaining 45% are red blood cells, white blood cells and platelets that are suspended in the plasma. Plasma is about 92% water.
5.There are three kinds of blood vessels: arteries, veins, and capillaries. Each of these plays a very specific role in the circulation process. Arteries carry oxygenated blood away from the heart.
6.The nasal septum is the cartilage and bone in your nose. The septum divides the nasal cavity (inside your nose) into a right and left side. When the septum is off-center or leans to one side of the nasal cavity, it has “deviated.” Healthcare providers call this a deviated nasal septum
7.stethoscope, medical instrument used in listening to sounds produced within the body, chiefly in the heart or lungs.
