Biology Organ systems course-Circulatory system,Excretory system, Respiratory system, Lymphatic System, Digestive system

Circulatory system-The heart is workaholic, Throughout our lifetime, it tirelessly pumps oxygen and nutrient-rich blood to all our body parts. This video explains the structure and function of the human circulation system. It explains how the human heart works and its structure.

Excretory system-The excretory system is the system of an organism's body that performs the function of excretion, the bodily process of discharging wastes. The Excretory system is responsible for the elimination of wastes produced by homeostasis.

Respiratory system-The respiratory system refers to the series of organs responsible for gas exchange in the body, which occur in presence of oxygen(aerobic respiration) and sometimes animals and plants cannot get enough oxygen to respire aerobically, such as during intense exercise, but they still need to respire to survive. After all, everything relies on the respiration for energy.

Lymphatic system-Lymphatic System supports cardiovascular function by collecting, filtering, and returning interstitial fluid back into the bloodstream via a system of lymphatic vessels. It also plays a major role in fighting infections.

Digestive system-Human Digestive System, the system used in the human body for the process of digestion. Digestion involves the breakdown of food into smaller and smaller components until they can be absorbed and assimilated into the body. I will be explaining the structures and the organs through which food passes through the system and gets absorbed into the blood and is distributed all over the body. The system also consists of structures through which waste passes in the process of elimination and other organs that contribute juices necessary for the digestive process.
