Ch 1
This type of joint allows movement in only one direction, like opening and closing a door.
What is a hinge joint?
This part of the blood carries nutrients and hormones.
What is plasma?
The center of an atom
What is the nucleus?
This organ, found near the stomach, helps filter blood and destroy old red blood cells.
What is the spleen?
These are microorganisms like bacteria and viruses that can cause disease in the body.
What are pathogens?
This connects two bones
What is a joint?
These blood cells fight off disease.
What are white blood cells?
These carry a negative charge and orbit the nucleus.
What are electrons?
These high-energy waves are used by doctors to see inside the body, especially to check for broken bones.
What are X-Rays
These artificial body parts are used to replace lost hands and can sometimes be controlled by muscle signals.
What are prosthetic hands?
The joint in your shoulder is an example of this joint type.
What is a ball and socket joint?
Red blood cells contain this oxygen-carrying protein.
What is haemoglobin?
These atomic particles have no charge.
What are neutrons?
This is the process of giving blood from one person to another, often used during surgery or after injury
What is blood transfusion?
These high-energy, negatively charged particles can be emitted from radioactive atoms.
What are beta rays?
The pair of muscles in your upper arm that work together to move the elbow.
What are biceps and triceps?
The circulatory system includes blood, blood vessels, and this muscular organ.
What is the heart?
The atomic number is the number of these in an atom.
What are protons?
These particles are large, positively charged, and were used in Rutherford’s gold foil experiment.
What are alpha rays?
This inherited disorder causes red blood cells to become crescent-shaped, leading to blockages and less oxygen transport.
What is sickle cell anemia?
These pairs of muscles work together by doing opposite actions to move a joint.
What are antagonistic muscle pairs?
These are responsible for forming clots when you get a cut.
What are platelets?
This early atomic model proposed that electrons were scattered in a sphere of positive charge, like fruits in a cake.
What is the plum pudding theory?
These are waves of electromagnetic energy released from atomic nuclei.
What are gamma rays?
This machine spins blood samples at high speed to separate plasma from blood cells.
What is a centrifuge?
