There is really no change in cardiac output, there is increased heart rate and a decrease in systolic volume.Although, it is common that after donating blood, vasovagal syncope occurs.
This is basically that the body reacts to de lack of volume, the brain detects an stimulator effect on the vagus nerve, lowers the heart rate and the person feels dizzy or falls, without major consequences.
Answer:
The motion of an object is defined by its change in position and direction.
Explanation:
Motion is the action of changing location or position. Motion is usually brought about by an external force.
Kinematics is the study of motion alone without regard to the forces or energies involved.
The various types of motion include:
Translational motion : This is motion that occurs along a straight line. For example, a car travelling on a straight road.
Rotational motion: this motion that occurs in a circular path. For example, movement of the earth round the sun.
Oscillatory motion: this is a periodic or to and fro motion that occurs between two points. For example, a swing or a simple pendulum.
Random or zigzag motion: This is motion that occurs in no particular pattern or direction. for example, the movement of dust particles.
Proteins are the building blocks of tissues responsible for building and growth. Proteins are also an important nutrient that supplies different body processes. These are compounds that are composed of chains of amino acids that are crucial in DNA-coding during the processes of cell division. They are considered as the building blocks of life and are in every cell of organisms. Humans depend on protein from food sources, mostly meat and poultry, which are responsible for repair and energy in muscles.
