Summary
Neonatal puppies and kittens have unique physiology impacting exams and lab tests. Understanding these key differences is crucial for accurate diagnosis and effective treatment in young dogs and cats.
Area of Science:
- Veterinary Medicine
- Neonatal Physiology
- Comparative Physiology
Background:
- Canine and feline neonates exhibit significant physiological changes from birth to weaning.
- Neonatal physiology differs markedly from adult physiology, despite their miniature adult appearance.
- These unique physiological characteristics influence clinical practice.
Purpose of the Study:
- To discuss the striking physiological differences between neonatal and adult canine and feline body systems.
- To highlight the clinical implications of these physiological variations.
- To provide a foundation for interpreting physical examinations and laboratory tests in neonates.
Main Methods:
- Review of existing literature on neonatal canine and feline physiology.
- Comparative analysis of physiological parameters in neonatal versus adult animals.
- Discussion of clinical case examples illustrating the impact of neonatal physiology.
Main Results:
- Neonatal physiology significantly impacts physical examination findings.
- Interpretation of laboratory test results requires consideration of age-specific norms.
- Diagnostic capabilities and therapeutic options may be limited by unique neonatal physiology.
Conclusions:
- Recognizing the distinct physiology of neonatal dogs and cats is essential for veterinary professionals.
- Understanding these differences improves diagnostic accuracy and treatment efficacy.
- This knowledge is critical for optimizing the care of young animals during the 4- to 6-week neonatal period.

01:14Fetal Circulation
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

01:25Physiological Barriers
Physiological barriers are semi-permeable cellular structures restricting drug diffusion into intracellular compartments and tissues. There are six types of physiological barriers: blood endothelial, cell membrane, blood-brain, blood-cerebrospinal fluid (CSF), blood-placenta, and blood-testis barriers.
The blood endothelial barrier is the most porous of these. It allows all small ionized, un-ionized, and lipophilic molecules to pass through the endothelial lining into the interstitial space...
