1. The right side of the mammalian heart pumps blood to the LUNGS. Here it absorbs OXYGEN and is now called OXYGENATED blood.
The gas, CARBON DIOXIDE is removed from the blood in the lungs. The blood returns to the LEFT side of the heart and from here it is pumped to the BODY TISSUES where it gives up its OXYGEN and is now called DEOXYGENATED blood. It passes back to the LEFT side of the heart in VEINS
2. Single Circulation -> The blood only passes through the heart once
Double Circulation -> The blood passes through the heart twice
3. Made of myocardium (thick muscle), four-chambered separated by valves, cardiac muscle is oxygenated via cornary ateries + veins, transports blood carrying oxygen + nutrients to the body's tissues
Answer and Explanation:
The pectorals major is an enormous, fan-formed muscle covering the chest. It is included clavicular and sternocostal areas. Adducts and turns the upper arm. Transverse adduction and flexion of the pectoralis major is smooth movement. You can see the muscles extending far and contracting back effectively.
The biceps brachii is a two-headed muscle. Despite the fact that most of the bulk is found anteriorly to the humerus, it has no connection deep down itself. The activity is Supination of the lower arm. It likewise flexes the arm at the elbow and at the shoulder. In the biceps brachil there isn't a lot of expansion found in the muscle contrasted with the pectoralis major.
