B.the beginning of a new or distinctive period
C. a molecule capable of acting as an enzyme
D. animal using only two legs for walking.
The correct answer is: right ventricle
There are two types of blood circulation:
1. Pulmonary circuit or circulation is a system of blood vessels between the heart and the lungs. In pulmonary circulation, deoxygenated blood leaves from the heart’s right ventricle through the pulmonary artery to the lungs. Oxygenated blood from the lungs (CO2 is released and O2 is picked up during respiration) is transported through the pulmonary vein and returned to the left atrium of the heart.
2. System circulation than transports oxygenated blood from the heart’s left ventricle through the aorta and to the rest of the body. Oxygen-poor blood from all tissues is then returned through the veins back to heart.
The body's nonspecific defiance against invading pathogens is known as innate immunity and includes the following:
mechanical barriers and surface secretions
1. The intact skin and mucous membranes of the body. These provide a high degree of protection against pathogens.
2. The sebaceous secretions and sweat of the skin contain bactericidal and fungicidal fatty acids that can kill bacteria and fungi.
3. Normal bacterial flora of the skin may produce various antimicrobial substances such as bacteriocines and acids.
Humoral defence mechanisms
1. Lysozyme. This is an enzyme found in most tissue fluids apart from cerebrospinal fluid, urine, and sweat. It can kill bacteria.
2. Interferon. Inhibits viruses from replicating
3. Complement. This is a heat labile serum that can destroy gram-negative bacteria.
