Digestive systems.

The digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the whole body. To achieve the goal of providing energy and nutrients to the body, six processes take place in the digestive system. ingestion secretion mixing and movement digestion absorption excretion There are 3 types of digestion:
Normal digestion - Breakdown of Carbohydrates, Proteins and Lipids to small solid substances that can be absorbed in the blood.
Mechanical digestion - physically breaking food down into smaller pieces.(teeth)
Chemical digestion - Breaking down food into simple substances using enzymes.

Cardiovascular systems.

The cardiovascular system consists of the heart, blood vessels and 5 liters of blood that the blood vessels transport. The cardiovascular system is transporting oxygen, nutrients, hormones and cellular waste products through the body. The cardiovascular system is powered by the hardest working organ the heart.

Circulatory Loops

Pulmonary circulation transports deoxygenated blood from the right side of the heart to the lungs where the blood picks up oxygen and returns

The respiratory and cardiovascular systems work together to perform the gas exchange function. Without gas exchange function, the cells would die, hence, it is needed for these systems to work together. Through respiratory system, the oxygen enters the body and then it is transported as oxyhaemoglobin to the cells with the help of cardiovascular system. The cardiovascular system also performs the work to transport the waste product carbon dioxide to respiratory system, that evacuates it. Hence, without respiratory system, the oxygen could not enter the body and it could not discharge the carbon dioxide waste. Without cardiovascular system, the oxygen and carbon dioxide could not travel the
