What is the order of the blood vessels as the blood leaves the heart, travels to a tissue, and then returns to the heart?
bazaltina [42]

The order of the blood vessels as the blood leaves the heart, travels to a tissue, and then returns to the heart is Aorta and Venacava.

Aorta and Venacava is the order of the blood vessels as the blood leaves the heart, travels to a tissue, and then returns to the heart.

The blood vessels in the order that it leaves the heart, goes to a tissue, and then returns towards the heart are the aorta and vena cava.

The principal artery that carries oxygen-rich blood from the heart to all of the body's organs and body parts is called the aorta.

The vena cava is the vein that sends the body's deoxygenated blood to the heart.

Blood that has been oxygenated is blood that incorporates oxygen. Blood that has been deoxygenated primarily contains carbon dioxide.

The aorta is the body's largest artery.

The pulmonary artery is where deoxygenated blood travels from the heart to the lungs.

The pulmonary vein is the vein that transports blood that has been oxygenated from the to the heart.

The tiny vessels, called capillaries, are present.

Blood must be pumped to all body parts for growth and life by the body's main pumping organ, the Heart.

The mammalian heart has four chambers, which prevent blood from mingling and effectively practice double circulation.

The same type of plants all year round on the same soil keeps on draining the land of the same nutrients needed for their growth. Rotation of different can help maintain soil nutrients level as some crop fixes nutrients in the soil.

Natural mulching

The use of cover cops as mulch helps protect the soil and allows for retention of nutrients. When cover crops are harvested the leaves can be turned back into soil to release nutrients that are stored up in the plant part.

Composting is the process of decomposing organic matter this could include animal waste such as dung,leaves both green and dead, kitchen. This waste are stored up, little water is added to moist and then allow to decompose it can be mixed together after few days to aerate after. After decomposing to form compost it can be added to the soil. It is usually rich in nutrients.
