Anaerobic is fermentation it doesnt use oxygen
Answer:
The human heart has four chambers. The right and left ventricles are the lower two chambers, and the right and left atria are the top two chambers. These four chambers are all connected by valves that control the flow of blood between them. The chambers and valves of the heart and all of the human body’s arteries and veins make up the human cardiovascular system.
Explanation: The right ventricle functions to perform two jobs. It receives from the right atrium blood that has had its oxygen removed by the body. The ventricle then pumps that blood into the pulmonary artery so it can be moved to the lungs.
The pumping that occurs in the ventricles requires more force than the pumping of the atria. This is because the blood travels outside the heart when leaving the ventricles. The aorta, on the other hand, pumps blood to a neighboring chamber. The ventricle’s need to pump the blood farther requires that the walls of the ventricles be thicker than the aorta walls.The heart is made of chambers that both hold and move blood, so there is a system of valves that prevents blood from moving in the wrong direction. Between the right atrium and the right ventricle is the tricuspid valve. The pulmonary valve is between the right ventricle and the pulmonary artery. These two valves keep the flow of blood going in one direction.The system moves blood in two parts. Contraction of the right atrium moves blood into the right ventricle via the tricuspid valve. The pulmonary valve is then closed and the right ventricle fills with blood.After the blood from the right atrium has moved into the right ventricle, the tricuspid valve closes so the blood does not flow backward. The right ventricle contracts and causes the pulmonary valve to open. The blood then moves freely to the lungs without possible backflow because the pulmonary valve closes after the ventricle has contracted completely.In some people, the ventricles can become enlarged, or dilated. Right ventricle dilation is rarer than left ventricle dilation. In either case, the size increase is generally a response by the heart to heal damage by thinning and stretching the muscle. If the heart has been damaged by previous heart attacks, alcohol abuse, exposure to heavy metals, or other harm, then there is a risk of ventricular dilation.
Synapse
It carries information through electrical impulses to the cell body.
It is the gap between neurons.
It ensures that information travels in one direction only.
Explanation:
A synapse is the gap or the junction where two or more neurons or nerve cells meet together.
Also called the synaptic cleft, the synaptic gap receives the electrical signals and passes them through one nerve cell to another
The axon nerve endings release neurotransmitters which ensure that the path of transmission of impulses is only unidirectional – only from presynaptic to postsynaptic path.
The synaptic gap between a nerve cell and an effector muscle cell is referred as the neuromuscular junction.
Answer:
Water and nutrient uptake.
Explanation:
The root system of a plant functions as conducting tissue for water and mineral nutrients that are essential for metabolic activities of the plant.
<em>Extensive surface area of roots is an adaptation associated with efficient water and mineral nutrient uptake because this will increase the surface area of roots in contact with the soil.</em>
