Study Notes

Multiple Choice Questions

Waste Removal System: The excretory system removes wastes.
Photosynthesis Location: Photosynthesis occurs in a plant's leaves.
Plaque Buildup Disease: Atherosclerosis is caused by plaque buildup.

Short Answer Questions

Leonardo da Vinci's Fame: Information missing.
Early Human Body Study Motivation: Information missing.
Circulatory System Transport: The circulatory system transports nutrients, wastes, oxygen & more.
Lungs' Gaseous Waste Product: The lungs remove carbon dioxide.
Respiratory & Circulatory System Interaction: They work together to supply oxygen to muscles.
Cellular Respiration vs. Breathing: Cellular respiration is an internal process; breathing is an external process with air intake & exhaust.
Chemical Digestion Location: Information missing.
Peristalsis Location & Function: Peristalsis occurs in the digestive system. It pushes food through the intestines.

Plant Organs & Needs

Plant Energy Source: Plants use their organs (like leaves, stems, etc) for this.
Tissue Function Description: Information missing.
Ethical Issue Definition: Information missing.
Organ vs. System Differences: Information missing.

Human Digestive System

System-Feeding Role: The digestive system feeds other bodily systems by breaking down food.
Increased Blood During Exercise: Muscles need more blood for increased energy.
Chloroplast Absence in Roots: Roots lack chloroplasts because they do not need them for photosynthesis.

Heart Valves

Importance of Valve Function: Functional heart valves are vital for blood flow.
Prosthetic Valves: Artificial valves can be synthetic or from animals (like pigs).

Sweating

Evaluation of Sweating: Sweating is a natural cooling mechanism, removing salt and heat, which is crucial for thermoregulation.

Teeth & Diet

Human vs. Canine Teeth Differences: Humans have a wider variety of teeth, better at varied diets, compared to canines, that are specialized for a different eating style.

Mangrove Salt Removal

Salt Removal System: Mangrove trees excrete excess salt through their leaves.
Human Equivalent Organ: Information missing.

Human Dissections

Importance of Early Dissections: Human dissections were important for understanding human anatomy and physiology.

Organ Donation Advantages/Disadvantages: Information missing.
Organ Donor Decision Explanation: Information missing.

Critical & Creative Thinking

**Creating a System Manual:**Information missing.
Human Body System Connections Concept Map: Information missing.

Research Topics

Smoking Bans: Impacts of second-hand smoke (environmental & health issues).
Rh Factor: Rh factor's role in blood groups (positive/negative).
Nitrogen Removal: Different methods animals use for removing nitrogenous waste.
Omega-3 Fatty Acids: Information about omega-3 sources, health benefits & reduced health threats.
