Answer:
PLATELETS
They have clotting factors that help along with calcium
Answer:
cell membrane
mitochondria
lysosomes
ribosomes
Explanation:
Cell membrane is the boundary of animal cell which is responsible for the intake of nutrients from outside environment of the cell. Cell membrane is a semipermeable membrane which take nutrient through a process of diffusion and active transport. Mitochondria is also called power house of the cell in which glucose molecule is broken down and energy is released. Lysosomes is an important organelle of the cell which is responsible for the collecting and removal of waste material from the cell through cell membrane. Ribosomes helps in the production of proteins and enzymes needed by the cell for different activities.
An atom of sodium has 11 protons, 11 electrons, and 11 neutrons.
Answer: the factors that increase cardiac output include:
--> Nervous stimulation and
--> Hypertrophy of the heart.
Explanation:
Cardiac output can be defined as the quantity of blood pumped into the aorta each minute by the heart. This is also the quantity of blood that flows through the circulation. There are factors that can cause increased cardiac output or that can lead to a hypereffective heart. They are:
--> NERVOUS STIMULATION: The combination of sympathetic stimulation and parasympathetic inhibition does two things to increase the pumping effectiveness or cardiac output of the heart. These include:
• it greatly increase the heart rate from the normal level of 72 beats/mum up to 180 to 200 beats /mom.
• it increases the strength of heart contraction, which is called increased contractility to twice it's normal strength.
--> HYPERTROPHY OF THE HEART: A long term increased workload, but not so much excess load that it damages the heart, causes the heart muscle to increase in mass and contractile strength in the same way that heavy exercise causes skeletal muscles to hypertrophy. This effect of increased muscle mass of the heart, allows the heart to pump much greater than usual amounts of cardiac output.
