What is the overall function of the cardiovascular system?
What is the overall function of the cardiovascular system?
The cardiovascular system is responsible for transporting blood throughout the body, delivering oxygen and nutrients to tissues and removing waste products.

Which three factors can cause resistance to blood flow through the vessels?
What is the purpose of the pericardial cavity?
What is the purpose of the pericardial cavity?
The pericardial cavity provides lubrication and protection for the heart, reducing friction as the heart beats.

Study Notes
Overview of Concepts
- This document contains study notes from a unit on transport in the body, covering blood and the cardiovascular system, and the respiratory system.
- Various objectives for each concept are included focusing on description, explanation, construction, and application of knowledge.
- Vocabulary terms, relating to components and processes within each body system are also included.
Concept 1: Blood
- Blood plays a critical role in maintaining homeostasis.
- Blood is composed of plasma, leukocytes, thrombocytes, and erythrocytes.
- The shape of a red blood cell (erythrocyte) contributes to its function.
- Hematopoiesis connects with other body systems.
- Steps involved in hemostasis are explained in detail.
- Eight different blood types in humans are detailed, along with the factors contributing to the different types and the implications of incorrect blood transfusions.
Concept 2: The Cardiovascular System
- The cardiovascular system uses the heart, blood vessels, and blood to maintain homeostasis.
- Factors causing resistance to blood flow are outlined.
- The location of the heart in the body is described through anatomical terminology.
- The purpose of the pericardial cavity is explained.
- The heart's interior, including atria, ventricles, valves, and major arteries and veins, and the function of valves are explained with descriptions and diagrams.
- The pathway of oxygen-poor blood transforming into oxygen-rich blood in the body is described.
- The differences in pulmonary, systemic, and coronary circulation are detailed.
- Cardiac muscle is unique from other muscle tissue.
- The cardiac conduction system works and the mechanism of heartbeats are explained.
- How the heart uses electrical and mechanical events in its cardiac cycle are explained.
Concept 3: The Respiratory System
- The respiratory system works with the cardiovascular system to deliver oxygen and remove carbon dioxide from the body.
- Conducting and respiratory zones and their structures are differentiated.
- The structure of lungs and bronchi are detailed.
- The pathway of air to reach the alveoli in schematic or flowchart format is presented.
- Alveolar sacs, and alveoli, are detailed through sketches or diagrams.
- The gas exchange in lungs and tissues is described.
- The role of the diaphragm is summarized.
- The relationship between volume, pressure, and air flow is explained.
- How inspiration and expiration work together to allow for breathing and how respiration is necessary for homeostasis is explained in cellular context .
- Students need to identify, and explain the functions of various respiratory system components.
