Answer:
1. The oxygen deprived cardiac muscles caused chest pain.
2. Unavailability of oxygen and blood supply to skin cells made them pale and cold.
3. Accumulation of blood in pulmonary circuit caused moist sounds.
Explanation:
The left ventricle receives oxygenated blood from the left atrium. Oxygenated blood from the lungs is carried to the left atrium by pulmonary veins. The left ventricle pumps the oxygenated blood to all body parts through the aorta. Failure of the left ventricle deprived the skin cells of oxygenated blood. Oxygen deficiency stopped energy production by cellular respiration. The result was pale and cold skin.
Failure of the left ventricle led to the accumulation of blood in the pulmonary circuit since the blood was not delivered to body tissues. The build-up of blood and resultant higher blood pressure caused moist sounds in the lower lungs.
The blockage of the coronary artery by a blood clot and death of a part of the heart due to lack of oxygen leads to a heart attack. The dead heart tissue is known as infarct and the resultant heart attack is myocardial infarction. Chest pain is caused due to the dead heart tissue or infarct.
It is called Maturation, Development, and Growth

Answer:
The circulatory system of a human compared to that of a frog is different due to the number of chambers. A frog’s heart has three chambers (two atria, and a single ventricle), whereas a human’s has four (two atria, and two ventricles). The atrium of a frog receives deoxygenated blood from the blood vessels that drain the various organs of the body. The left atrium receives oxygenated blood from the lungs and skin.
Cell division is known as how organisms grow and repair themselves.
For example the parent cell divides forming 2 daughter cells identical to the parent.
