Explanation:
There are different types of biological tools, with each of them having different functions. However, for the sake of the question, some of the popular tools will be listed here.
1. Stockroom tools: this includes:
Beaker: this is essential to take or storing small substances
Bunsen Burner: this is important in the biological lab to heat a substance
Flask: this is essential in holding liquid substance.
Pipette: it forms of a lab spoon that is used in mixing substances to form a compound or mixture
2. Computer and Imaging system: this is important in image analysis and sequence-analysis programs
3. Cell cultures: this is used in the biological lab to enhance the complex cell differentiation required in the experimentation of animal cell structure
4. Microscopes: this is essential in determining and examining the microscopic organism that we can not see with our makes eyes
Answer:
its mass is the answer I just look up some research
Answer:
1. Aortic semilunar valve
2. Tricuspid valve
3. Mitral valve
4. Pulmonary semilunar valve
5. Mitral Valve
6. Tricuspid valve
Explanation:
The four heart valves of our heart have two main functions. They open to allow blood to pass through them, and close to prevent blood from going back (backflow).
Semilunar valves:
There are two semilunar valves and they have 3 cusps. They open up to areas outside the heart. Their main function is to prevent backflow towards the heart.
a. Aortic semilunar valve is located in between the Aorta and the left ventricle. It opens up to the Aorta where oxygen-rich blood leaves the heart and go towards the other parts of the body. It prevents backflow to the left ventricle.
b. Pulmonary semilunar valve is located in between the right ventricle and the pulmonary artery. It opens up to the pulmonary artery which carries unoxygenated blood towards the lungs. It prevents backflow to the right atrium.
Atrioventricular valves:
They are named as such because they are found in between the atria and the ventricles.
a. Tricuspid valve has three cusps and it is found on the right side of the heart. It is located in between the right atrium and the right ventricle. It prevents backflow to the right atrium.
b. Mitral valve has 2 cusps and that is why it is also known as the bicusip valve. It is located in between the left atrium and the left ventricle. It prevents backflow to the left atrium.
