Answer:

The human circulatory system is involved in the pumping blood from the heart to the different parts of the body. It consists of the heart and the blood vessels.

Blood rich in oxygen from the left atrium move into the left ventricle of the heart and is pumped into the aorta, which is a very large and elastic artery. The aorta carries the oxygenated blood to the thoracic and abdominal cavities where they are supplied to all organ systems by the arterial branches from the aorta.

Tisusue metabolism in the organ systems causes low content of oxygen and high content of CO2. This blood is called deoxygenated blood and is returned to the right atrium of the heart. The blood then enters the right ventricle. It is pumped into the pulmonary trunk and arteries. The blood is then transported to the lungs where gaseous exchange occurs between the lung capillaries and the alveoli of the lungs.

The oxygenated blood is then transported to the organ systems and the cycle continues.

Nastasia [14]

Answer:

Steps to follow:

Make an observation: An observation would be made on how water is been used in the house and how it can be conserved, this observation is what brings about the question asked

Ask a question : The question is

which is more effective in conserving water a misting shower head or regular shower.

Form a hypothesis, or testable explanation: An hypothesis is formulated for the question asked

Example: Null hypothesis: Mistling shower conserves more water than shower head

Alternative: Mistling shower conserves less water that normal shower.

Make a prediction based on the hypothesis: Predictions are made on what could be the cause if there is indeed a difference and what could cause the difference

Test the prediction: An experiment is conducted to test the hypothesis if indeed Mistling is better than normal shower, the appropriate method is determined to be used for the experiment.

Iterate: The result gotten helps to butters our hypothesis if its to be acceoted or rejected. If rejected further research can be conducted on the effectiveness of normal shower in conserving water.
