Bones
The longest bone in the human body.
The femur.
This muscle is the primary agonist responsible for elbow flexion.
Biceps Brachii
This type of synovial joint allows rotational movement around a single axis and is found between the atlas and axis vertebrae.
Pivot Joint
These blood vessels contain valves, have relatively thin walls, and return blood to the heart under low pressure.
Veins
This structure is commonly known as the windpipe and carries air from the larynx to the bronchi.
Trachea
Unlike its neighbouring forearm bone, this bone is located on the medial side of the forearm in anatomical position and forms the prominent point of the elbow.
Ulna
This muscle is responsible for abducting the arm at the shoulder and is commonly targeted during lateral raises
Deltoid
This joint type is found between the carpal bones of the wrist and allows small gliding movements.
Gliding Joint
This component of blood is responsible for transporting oxygen by binding to haemoglobin.
Red Blood Cells
These tiny air sacs are the primary site of gas exchange in the lungs.
Alveoli
This bone is found in the upper arm and articulates with the scapula at the shoulder.
Humerus
This muscle runs vertically along the anterior abdominal wall and is primarily responsible for trunk flexion, such as when performing a sit-up.
Rectus Abdominus
These strong bands of connective tissue connect bone to bone and help stabilise a synovial joint.
Ligaments
This term refers to the volume of blood pumped by the heart each minute.
Cardiac Output
This muscle contracts and flattens during inspiration, increasing the volume of the thoracic cavity.
Diaphragm
The scapula and sternum belong to this category of bone, which primarily protects internal organs and provides broad surfaces for muscle attachment.
Flat Bones.
This muscle crosses both the knee and ankle joints, contributing to knee flexion and plantar flexion.
Gastrocnemius
This type of synovial joint is found at the wrist and allows movement in two planes, including flexion, extension, abduction, and adduction.
Condyloid Joint
This chronic adaptation increases the amount of blood pumped from the left ventricle with each heartbeat, allowing the heart to work more efficiently during exercise.
Increased Stroke Volume
This process describes the movement of oxygen from the alveoli into the blood and carbon dioxide from the blood into the alveoli.
Diffusion/Pulmonary Diffusion
The section of the vertebral column consisting of five vertebrae located in the lower back.
Lumbar
During the downward phase of a squat, the quadriceps are primarily performing this type of contraction.
Eccentric
This fluid reduces friction between the articular surfaces of bones within a synovial joint.
Synovial Fluid
If these blood vessels become blocked, the heart muscle may be deprived of oxygen, potentially leading to a heart attack.
Coronary Artery
This measure represents the difference in oxygen content between arterial blood and venous blood and indicates how much oxygen has been extracted by the muscles.
